[Problems to be solved by the invention]

 In the above-described conventional automatic car wash brush, a material such as a synthetic resin foam, which can be divided into slits 5 and formed into a substantially prismatic shape, is used as the material of the brush piece 3. However, when various types of dirt are adhered to the surface to be cleaned, the dirt that is difficult to remove with the synthetic resin foam as described above sometimes remains without being completely removed. In such a case, if the surface to be cleaned is cleaned again with a cleaning apparatus having a cleaning brush using a material different from the material of the brush, the dirt may be removed. However, cleaning again with a different cleaning device is extremely impractical and time-consuming, and incurs the cost of using a different cleaning device again. Therefore, there has been a demand for a cleaning brush that can quickly and accurately remove stains on a surface to be cleaned without using a different cleaning device again.

[Embodiment of the invention]

 3 to 5 show the embodiment. FIG. 3 is a perspective view of the cleaning brush of the present invention viewed from the front side. In FIG. 3, 11 is a cleaning brush, 12 is a rotating shaft, 13, 14, and 15 are brush pieces, 16 is a slit, 17 is a circular hole, 18 is a stopper, and 19 is a groove. FIG. 4 is a perspective view of the brush piece used for the cleaning brush of the present invention as viewed from the front side. In FIG. 4, 21 is an end. FIG. 5 is a perspective view of the brush piece used for the cleaning brush of the present invention as viewed from the front side. In FIG. 5, 22 is an end, 26 is a slit, and 27 is a circular hole.

As shown in FIG. 3, the cleaning brush of the present invention is formed by a rotating shaft 12, a brush piece 13, and a stopper 18. The rotating shaft 12 has a substantially cylindrical shape made of metal, and grooves 19 are formed on its outer periphery at four equally-spaced portions so as to be parallel to the longitudinal direction of the rotating shaft 12. The brush piece 13 is composed of brush pieces 14 and 15. The brush piece 15 is formed by sandwiching the brush piece 15 from both sides and then folding the central portion. After the mounting, it is mounted so as to be formed at four equally spaced parts in the groove 19.

As shown in FIG. 4, the brush piece 14 has a plurality of slits 16 formed from the end portion 21 toward the rotation shaft side, and the other end of the slit 16 communicates with the slit 16. A circular hole 17 is formed. As the material of the brush piece 14, a synthetic resin foam is used. As shown in FIG. 5, the brush piece 15 has a plurality of slits 26 formed from the end 22 toward the rotating shaft, and the other end of the slit 26 communicates with the slit 26 to form a circular hole 27. Is formed. As the material of the brush piece 15, a non-woven fabric of natural cellulose is used.

Since the cleaning brush according to the embodiment of the present invention is configured as described above, when the cleaning brush is used, the brush piece 14 formed of a synthetic resin foam and the natural cellulose nonwoven fabric are used. The formed brush piece 15 can simultaneously contact the surface to be cleaned and be cleaned. Therefore, the properties of the synthetic resin foam such as weather resistance and abrasion resistance, the properties of natural cellulose non-woven fabric such as water-absorbing properties, and the high level of dirt trapping power due to the uneven surface structure are evaluated for the surface to be cleaned. At the same time and appropriately. In addition, since the brush piece 13 is formed in a structure in which the brush piece 15 is sandwiched between the brush pieces 14 from both sides, the brittleness, which is a property of the non-woven fabric of natural cellulose, is less than that of the synthetic resin foam. Protected by the high weather resistance, which is the property of having the property, the product life of the brush piece 15 formed by the structure sandwiched between the brush pieces 14 from both sides can be reduced, so that the brush piece 14 is not sandwiched. It can be extended as compared with the case where it is formed in advance.

The cleaning brush according to the embodiment of the present invention is configured as described above. However, regarding the material used for the brush piece, the sandwiching structure, the shape of the brush piece, the number of slits, the material of the rotating shaft, and the like. Depending on the condition of the surface to be cleaned, for example, brush pieces using three different materials may be alternately overlapped, or the height of the end of the brush piece may be adjusted according to the characteristics of the material used. Alternatively, there is no problem even if a method of appropriately setting the number of slits and forming a brush piece having a different end height or a different number of slits depending on the material is used. Also, the number of grooves may be set appropriately, for example, at 6 or 8 equally spaced parts according to the purpose, without any problem.

Next, FIGS. 6 to 8 show other examples of the embodiment. FIG. 6 is a perspective view of a cleaning brush according to another embodiment of the present invention as viewed from the front side. In FIG. 6, 30 is a pedestal, 31 is a cleaning brush, 32 is a rotating shaft, 33 and 34 are brush pieces, 38 is a stopper, and 39 is a channel brush. FIG. 7 is a perspective view of a brush piece used for a cleaning brush according to another embodiment of the present invention as viewed from the front side. In FIG. 7, 35 is an end face. FIG. 8 is a perspective view of a brush piece used for a cleaning brush according to another embodiment of the present invention viewed from the front side. In FIG. 8, reference numeral 36 denotes an end face.

As shown in FIG. 6, a cleaning brush according to another embodiment of the present invention includes a rotating shaft 32, a stopper 38, and a channel brush 39. The rotating shaft 32 has a substantially cylindrical shape made of metal, and a channel brush 39 is formed so that the rotating shaft 32 is spirally formed by applying a twist around the outer periphery of the rotating shaft 32. The channel brush 39 is formed by brush pieces 33 and 34 and the pedestal 30, and is fixed to the rotating shaft 32 by a stopper 38. The brush pieces 33 and 34 are alternately formed so as to have a predetermined thickness in the longitudinal direction of the rotating shaft 32.

As shown in FIG. 7, the brush piece 34 has a substantially rectangular shape, and is made of a synthetic resin foam. As shown in FIG. 8, the brush piece 33 has both end faces 36 that are pre-cracked and a roughly long shape having a cross-shaped cross section. Chemical fiber is used.

Since the cleaning brush according to another embodiment of the present invention is configured as described above, when the cleaning brush is used, the brush piece 34 made of synthetic resin foam is used. In addition, the brush piece 33 formed of the chemical fiber in the form of a film can be cleaned by simultaneously contacting the surface to be cleaned. Therefore, the properties of the synthetic resin foam, such as weather resistance and abrasion resistance, and the property of the film-like chemical fiber, the high detergency, are simultaneously and appropriately applied to the surface to be cleaned. Can work. In addition, by bringing the synthetic resin foam and the film-like chemical fiber into contact with the surface to be cleaned at the same time, the low durability of the film-like chemical fiber is reduced. In addition to the high abrasion resistance that can be compensated for, the low detergency of fine stains, which is a property of synthetic resin foam, and the cracked end face structure, which is a property of film-like chemical fibers. The high detergency against fine dirt can compensate for this. Therefore, the cleaning brush according to another embodiment of the present invention using the synthetic resin foam and the film-like chemical fiber is different from the case where only the synthetic resin foam or the film-like chemical fiber is used. Thus, the durability of the brush piece can be improved.

The cleaning brush according to another embodiment of the present invention is configured as described above. However, the material used for the brush piece, the structure to be sandwiched, the shape of the brush piece, etc. Depending on the condition of the surface to be cleaned, for example, use a brush piece with the cross section of the film-like chemical fiber set in a roughly corrugated shape, or alternately form brush pieces of a different material in the longitudinal direction of the rotating shaft. There is no problem even if the predetermined thickness is set arbitrarily. Further, there is no problem even if a channel brush formed by alternately sandwiching brush pieces of different materials by a predetermined number on the pedestal is used. Furthermore, there is no problem in using a channel brush formed by arbitrarily mixing brush pieces of different materials and then sandwiching the pedestal.

[Effect of the invention]

 Since the cleaning brush according to the embodiment of the present invention is configured as described above, when the cleaning brush is used, a brush piece formed of a synthetic resin foam and a non-woven fabric of natural cellulose is to be cleaned. The surface can be contacted and cleaned at the same time. Therefore, the properties of the synthetic resin foam, such as weather resistance and abrasion resistance, and the properties of natural cellulose nonwoven fabric, such as the water-containing property and the high dirt trapping power due to the uneven surface structure, are determined by the surface to be cleaned. At the same time and appropriately. In addition, the non-woven fabric of natural cellulose having brittleness is protected by being sandwiched from both sides by a synthetic resin foam having high weather resistance. The durability of the natural cellulose nonwoven fabric can be extended.

Further, like the cleaning brush according to another embodiment of the present invention, brushes of different types of materials are formed on the outer periphery of the rotating shaft so as to alternately form a predetermined thickness in the longitudinal direction. When the channel brush is formed spirally by twisting around the axis, the brush pieces made of synthetic resin foam and film-like chemical fiber simultaneously come into contact with the surface to be cleaned. Can be washed. Therefore, the high weather resistance and abrasion resistance of the synthetic resin foam and the high detergency of the film-like chemical fiber simultaneously and appropriately affect the surface to be cleaned. Can work. In addition, by bringing the synthetic resin foam and the film-like chemical fiber into contact with the surface to be cleaned at the same time, the low durability of the film-like chemical fiber is reduced by the property of the synthetic resin foam. The abrasion resistance can be compensated for by the high abrasion resistance, and the low detergency of fine soil, which is a property of synthetic resin foams, is due to the end face cracking structure, which is a property of film-like chemical fibers. The high detergency against fine dirt can be captured. Therefore, the durability of the brush piece formed from the synthetic resin foam and the film-like chemical fiber can be improved as compared with the case where only the synthetic resin foam or the film-like chemical fiber is used.
